lampreys in small creeks???

14 posts in this topic

I fly-fished crooked creek, near hinckley, on saturday the 13th. It is a small creek that flows into the st. croix, and has a few trout in it...but I also saw a few small creatures swimming in the creek that looked like eels. they were about 6" long, and I saw one attached to a decent sized trout. It reminded me of pictures i've seen of lampreys attached to lake trout in lake superior.

Anyways I'm just wondering if anyone else has seen this, because I wouldn't have expected lampreys to be invading small streams.

They are natural to the streams according to the DNR.

They are listed on the rare fish web page. With their status level as, "special concern". They have Northern and Southern Brook Lamprey listed there.

A friend of mine caught one out of the Sunrise River a few years ago.

They breed in streams near bigger water and venture out after. The DNR dumps lampreycide in creeks to kill about 90 percent of fry to keep the numbers down. I have caught fish with those attached in Lake Superior and in the St Croix near Stillwater. I will admit how strange it is to look eye to eye with a parasite. Yuck.

i guess i wasn't aware that lampreys lived in waterways other than the great lakes. i have to agree that parasites are a little gross...I thought about reaching down and grabbing one of them but chickened out!

It is good to hear that the DNR is making attempts at reducing their population. Does anyone know what effects they have on fish when attached?

I think they are trying to save the ones in the St Croix and eliminate the ones in Superior. Two differant species.

They look like something you would see in a science fiction movie like an alien with a bunch of teeth that are in a circular shape that want to eat you! sick

They are brook lamprey. They are non-parasitic. I found the following from a DNR paper.

"The northern brook lamprey (I. Fossor) occurs in the Blackhoof Creek in the Lake Superior drainage. The southern brook lamprey (I.gagei) has been found in five streams in the St. Croix River drainage."

I have shocked streams in northern wisconsin (far from any major rivers or great lakes) that were chock full of them.

Here is a link to the DNR paper. http://files.dnr.state.mn.us/eco/nongame/projects/consgrant_reports/1987/1987_cochran.pdf

    • Was doing some work in the woods today and found these. Of course I stopped and spent two hours looking for more, but this was it. Oh well, will probably be the earliest I've ever gotten to eat them.  
    •   I would definitely get the one with the Pheasant plowing attachment! Beats walking the fields!
    • Never getting rid of my Suburban. Just looking for a new toy for hunting etc. that I can drive down narrow dirt roads up north. Another reason why I would rather buy a slightly used one so I can use it without worrying about putting a few scratches on it. Those side by sides look like fun but you have to haul them around and cant drive them everywhere. And they just aren't built to take what a Jeep can. Always kind of liked the looks of Jeeps and being able to remove the top in the summer is nice to. Would definitely want a hard top to as the soft tops aren't to good for MN winters. I'm sure the newer ones have better heaters than the older ones as I remember back in the day guys were dressed like they were snowmobiling while driving their Jeep. And scraping frost off of the window to see.
    • I went through the same thing. I had ATV's at first then bought an RZR. It was fun but honestly the quality for the price is pretty bad. You can go up to a Can Am but then the price is even worse. So a few years after I sold the RZR I got the itch again but then started looking at the Wranglers and ended up doing that. I bought a 2006 with the 4.0 and after that and buying a used 6.6' plow I was into it for less than 13.5k and can drive it everywhere.   I have the hardtop on mine. I just take it off in the summer and drive it when it's nice. IMHO it's the way to go but you need to watch out for ones that are rusted out. I take the doors off, the top off and drive around sniping gophers, head to the lake or just cruise around. I like the 32" BFG KO tires.     
    •   What's a big guy like you going to do with a little SUV?  Your still keeping the truck to pull that new trailer right?
    • Good luck, have fun and stay topside this time of year.
    • Did you have to sand in between coats of lacquer? I was going to use a pre catalyzed lacquer for a little more durability, but it seems like it would take forever to get in all of the grooves. 
    • Some of the older ones had a 4 cylinder. Think the new ones only have a 6 now.
